Ancient faults that formed in the ocean floor millions of years ago are feeding earthquakes today along stretches of the Alaska Peninsula, and likely elsewhere, a new study suggests.
With Chapala’s destructive landfall in Yemen just a couple of days in the past, a second tropical cyclone, Megh, has just formed in the Arabian Sea. This one is not forecast to become anywhere near as intense as Chapala did—though we know intensity forecasts can be wrong, as they were at early stages for both Chapala and Patricia.
Hurricane Patricia, the strongest hurricane ever observed in either the Atlantic or eastern Pacific, is expected to make landfall on the Southwest coast of Mexico this afternoon and evening as an extremely dangerous Category 5 hurricane.
Heading out to our field area, we discovered that the abandoned river valley we planned to study was completely flooded. There was pani—the Bangla word for water—everywhere.
Returning to Bangladesh for additional fieldwork, I stopped off in India for several meetings, but we found time for some sightseeing, too. We were able to see the Qutub Minar complex in Delhi as well as the Taj Mahal and Agra Fort in Agra. Plus all the meetings in Delhi, Kolkata and Dhaka were very successful.

The SEDAC Hazards Mapper is designed for disaster risk managers, humanitarian response organizations, public health professionals, journalists and others needing a quick assessment of the potential dangers posed by a major hazardous event or developing emergency.
Even the simplest research questions can lead to far-reaching public benefits. Consider Chris Small and Joel Cohen’s study of global population by altitude, being honored this week at the Library of Congress.
Lamont’s Einat Lev and Elise Rumpf write about their expedition to the lava fields of Iceland, where the two volcanologists and a drone named Buzz studied how lava flows and what happens to rivers, rocks and old lava in its path.
